Application December 2,

1 Claim.

This invention relates to a heat radiation device for rooms of dwellings and other buildings and has for the primary object the provision of an efficient and inexpensive heat radiation device which may be readily set up in a room and will simulate a fireplace with burning logs therein supported by log irons as in a real fireplace, the device being connected in the heating system of the dwelling or building so that heat may be derived therefrom with a realistic effect of a burning fireplace which besides efficiently heating the room adds attractiveness and satisfying comfort to the room.

Another object of this invention is the provision of a heat radiation device of the above stated character wherein liquid fuel may be burned therein and in such a way as to simulate burning logs.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure l is a front elevation illustrating a heat radiation device constructed in accordance with my invention.

Figure 2 is a rear elevation, partly in section, illustrating the same.

Figure 3 is a sectional view taken on the line 33 of Figure 1.

Figure 4 is a front elevation partly in section illustrating a modified form of my invention.

Figure 5 is a sectional view taken on the line 5 5 of Figure l.

Figure 6 is a fragmentary rear elevation, partly in section, showing the connection between the heat radiation device simulating logs connected to a heat conduit.

Figure '7 is a front elevation illustrating another modified form of my invention.

Figure 8 is a sectional View taken on the line 3-8 of Figure '7.

Figure 9 is an end elevation of the form of my invention shown in Figures '7 and 8.

Figure 10 is a detail perspective View, illustrating the connection between the fuel valve and the operating means.

Referring in detail to Figures 1 to 3, inclusive, of the drawings, the numeral ii indicates a shell or casing which may be readily set up in a room by resting on the floor of the room, as indicated at 6, with the back of the casing or shell dis- 1938, Serial No. 243,669

posed next to a wall of the room. It is preferable that the shell or casing represent in design a wall of a fireplace having the usual fireplace opening Z in the front thereof in which is positioned andirons or log supporting irons indicated by the character 3 and arranged thereon is a heat radiation member 9 shaped to represent several logs 9 positioned horizontally with one log resting upon the other logs. The logs 9 are of hollow formation defining heat chambers communicative with one another and to which heat supply pipes ill are connected for directing therein heat in the form of hot water or steam obtained from a heating systemof the dwelling or building. One of the pipes Ill includes a control valve ll.

Arranged'on the heat radiation device 9 is a series of electric lamps l2 preferably colored and each of a small candle power and electrically con- -nected to electric feed conductors l3 arranged in rear of the heat radiation device 9 and forming part of an electric circuit (not shown). The conductors it have connected thereto a switch unit M preferably of the type including a series of manually operated switches whereby the electric lamps may be made to illuminate simultaneously by closing all of the switches or certain groups of the lamps may be made to illuminate while other groups of lamps are non-illuminated or all lamps may be turned out.

The electric lamps when illuminated will cast a colored light over the heat radiation element or member 9 so as to produce the effect that the member or element 9 is burning in a flame. The heat passing off of the member or element 9 may readily enter the room in which the device is located for the heating of the room.

The casing or shell 5 is preferably designed in such a way as to represent a wall of slab formation or, if desired, may be, designed to represent stonework, brickwork, or any other type of ornamentation found in the wall construction of a fire place.

Formed in the front wall of the shell or casing above the fireplace opening 1 is a heat chamber !5 consisting of a series of communicating compartments and the chamber E5 is connected to the heating system by the pipe l6 so that steam or hot water may enter the chamber l5 whereby heat will radiate from the front wall of the shell or casing.

As shown in Figures 4 to 6, inclusive, the device may consist of a shell or casing l I representing a fireplace having a mantel 88 with the walls of the fireplace simulating bricks, the fireplace opening being indicated by the character l9 and has a heat radiating element or member 20 therein supported by the irons 2| and of a shape to represent grouped horizontally arranged logs. The member 2|] is of hollow formation and the walls are provided with a'series of perforations 22 to allow heat from within the member 20 to escape. The member 20 is connected by a T-shaped pipe 23 to a hot air conduit 24 equipped with a valve 24. A heating radiator 25 is arranged vertically in the fireplace opening rearwardly of the member 20 and extends above the latter and is in the form of a perforated casing connected to a hot air conduit 25' in which is located a valve 26'.

It is to be understood that the conduits 24 and 25 are to be connected to a hot air furnace or similar heating plant.

The member 20 is equipped with the series of electric lamps l2 for the purpose of illumination and giving the efiect to the member 20 of burning in a flame.

Referring to my modified form of invention, as shown in Figures '7 to 9, inclusive, a casing 26 is provided having the general outline of a fireplace including a mantel 2'! and opposite ends of the casing are equipped With doors 28 hingedly mounted so that they may be readily opened to give access to the interior of the casing. The front Wall of the casing has a fireplace opening normally closed by a removable transparent panel 29. Located within the fireplace chamber of the casing is a heat radiation member 30 of the formation to represent grouped logs supported by log irons 3! and positioned under the member 30 is an oil burning pot 3! adapted to be fed with fuel oil from a pipe 32 leading to a reservoir 33 and having therein a control valve 34 which may be opened and closed by an operating means 35 positioned so as to be conveniently actuated from within front of the casing, as clearly shown in Figures 7 and 8. By referring to Figure 8 it will be seen that the casing fits against the wall and rests upon the floor of the room and the fireplace chamber therein has connected thereto a smoke pipe 36 extending out of the room.

With the fuel oil burning within the pot 3| the flames pass about the member 30 giving the effect of burning the member 30 which is in the form of grouped logs besides casting off a desired heat.

It is believed that the simplicity and advantages of this invention will be perfectly apparent to those skilled in the art to which such device relates, and while I have herein set forth a satisfactory'embodiment of the invention, it is to be understood that such changes therefrom as fairly fall within the scope of my claim may be resorted to when desired.

What I claim is:

In a heat radiation device of the class described, a shell including side, front and top walls of integral construction, said front and side Walls converging toward the upper ends, said top wall having a curvature thereto for merging into the front and side walls, said front Wall having an opening extending through the lower edge of said front wall to form a fireplace opening, said front wall between the fireplace opening and the top Wall having a series of communicating chambers to form a heat radiating portion to said shell, a hollow heat radiation member arranged horizontally in the fireplace opening and shaped to resemble a plurality of stacked logs, and means for providing a circulation of heating fiuid through said member and the heat radiating portion of the shell.
